' Be it known that I, HERBERT A. PUL

United States, and a resident of Eustis, in the county of Lake and State of Florida, have invented certain new and useful Improvements in Attachments for Gatherers on Sewing Machines, of which the following-is a specification.

This invention relates to attachments for gatherers on sewing machines.

The object of the invention is to provide an attachment of the above character which is adapted for ripping a seam in cloth in an expeditious and efficient manner.

Other objects and objects relating to details of construction, combination and arrangement of parts will hereinafter appear.

The invention is illustrated by way of example in the accompanying drawings, in which- Figure 1 is a detail elevation showingmy invention applied,

Figure 2 1s a horizontalv sectional view taken substantially on the line 2--2 of Figure 1,and illustrating the manner in which the attachment is secured to the gatherer.

Figure 3 is a top plan view of the ripping attachment with the knife guard and shoe removed."

Referring to the drawings more particularly, 10 indicates the portion of the sewing machine which carries the needle reciprocating member 11 and the presse-r foot stem 12. In the present instance, a gatherer generally indicated at A is shown as, attached to the reciprocating member 11 and stem 12 in the usual manner. The general and operation of the gatherer is well known but for illustrating the present invention it ma be mentioned that -13 is the presser foot of the gathere'r; 14 the gatherer bar which is reciprocated by the reciprocating movement of the member 11 of the sewing machine, and 15 the supporting frame member of the gatherer.

The present seam ripping attachment for the gatherer A comprises a base plate 16 which has formed therewith at its one end an arm 17, said arm extending at right angles to the plate and being formed with an upwardly bent portion 18 and a portion 19 extending forwardly from said upwardly bent portion 18. The portion 19 is formed at its end with a semi-circular notch 20, and

construction also forni'edh with a tang or lug 21 the one side thereof, andsaid tang beingin turn provided with a U-shaped recess 22.

The arm 17 is connected tothe presser foot of the gatherer as at 27 by a-screw 23, said screw beingpositioned in he notch 20, and the tang 21 is likewise connected with the frame member 15 of the gatherer. obvious by this arrangement of securing the plate 16' to the gatherer by slightly loosening the screws 23 and 24: thesamenmay'be quickly attached or detached.

Upon the plate 16 blade 25 by ,the means of-the pin 25,. -The knife blade being rounded at itsouter end and formed with a cutting edge as at 26. Upon the inner end of the knife blade there is; secured an arm 26, said arm extending there is pivoted a knife transversely thereof, and being pivotally connected to a link 27 by a pin 28, and said link beingyin turn pivotally connected to the journal orcrank ;pin 29- of the gatherer bar 1 1. As is obvious by the construction provided the reciprocating movement of the gatherer bar 14eis1transmitted to the knife blade 25 for oscillating the same.

Upon the lower faceorside-of the plate 16 there issecured a shoe 29 which comprises a semi-circular portion 30 which terminates in an upwardly and forwardly curvedportion] 31, the curved portion 31 extending over the cutting blade as shown and the forward end of the cutting blade extending through a transverse slot formed in the portion 31 of the shoe. 2

In the operation of the present device, when it is desired to rip a seam, an end portion of the seam is first ripped by hand so that the shoe 29 may be slipped between the plies of cloth which seam. The divided plies are then brought together and positioned beneath the presser foot 13 so that as the'machine is operated the cloth will be drawn forwardly with respect to the cutting blade 25. The cloth is of course to be guided so that the cutting edge 26" of the blade will operate upon the threads of the seam and sever" them as the cloth moves forwardly with respect thereto.

While I have shown the preferred form of my invention it is to be understood that I am aware of the fact that the construction, combination and arrangement of parts may be slightly changed are secured by the for producing the same results by those skilled in the art without departing from the spirit of my invention as indicated by the appended claims.

I claim:

l.-. In asewing machine provided with a gatherer, a reciprocating member for the gatherer, a seam ripping attachment comprising a base plate connected'to said gatherer and extending rearwardly therefrom, an elongated blade having its one end pivo ted to said base plate and its other end extending rearwardly therefrom, said extended end of the blade being formed with a cutting edge, and connecting means hetween'sa'i d blade and the reciprocating mem- 7 her of said gatherer whereby the free end of said cutting blade may be oscillated.

2. In a sewing machine provided with a gatherer, a reciprocating member for the gatherer, a seainripplng attachment comprising a base platedetachably connected to said gatherer and extending rearwardly therefrom, an elongated blade having its one. end pivoted to said base-plate and its other end extending rearwardly from said 7 plate,' saidextended end of the blade being formed with. a cutting edge, connecting means between said blade and the recipro eating member of the gatherer whereby the free end of said blade may be oscillated, and

Q a'shoe carried by said base plate.

'3. .I n a sewing machine provided with a gatherer, "a reciprocating member for the gatherer', a seam ripping attachment compri singfa' blade, and connecting means between the reciprocating member of said gatherer, and theblade of said ripping attachment whereby the blade will be oscillated through the reciprocating member of the gatherer, a v 4,111 a sewing machine provided with a gatherer, an operating member for the gatherer, and a seam prising a seam severing member adapted to be operated through the operating member of the gatherer.

'5. In a seam ripping device of the character described, a shoethaving a rounded face, a blade having a cutting edge extending through a slot in said rounded face, and means whereby said blade may be oscillated for severing a seam presented thereto.

6. In a seam ripping device of the charac tcr described,a circular shoe member having a transverse slot therein, said slot occurring above the engagement portion of the shoe member, a blade extending through said slot and formed vith a cutting edge, and means for oscillating said blade whereby to sever threads presented thereto.

7. In combination in a sewing machine, an attachment i-ncluding'a shoe having a rear rounded face, said face being formed with a slot, a cutting blade extending through said slot and having an edge adapted to sever threads presented thereto, and means for oscillating said blade,

ripping attachment com- 8. In combination in a sewin machine an attachment including a shoe having a rear rounded face, said face being formed with a slot, a cuttingblade extending through said slot and having an edge adapted to sever threads presented thereto, and means adapted to be driven from the middle reciprocating member of the sewing machine whereby said blade will be oscillated.

9. In a sewing machine provided with a gatherer, an operating member for the gatherer, and a seam ripping attachment comprising a blade adapted. to be oscillated through .the operating member ofthe gatherer.
